=== ISO/IEC 8859-15 ===
[[ISO/IEC 8859-15|ISO/IEC&nbsp;8859-15]] was developed in 1999, as an update of ISO/IEC&nbsp;8859-1. It provides some characters for French and Finnish text and the [[euro sign]], which are missing from ISO/IEC&nbsp;8859-1. This required the removal of some infrequently used characters from ISO/IEC&nbsp;8859-1, including fraction symbols and letter-free diacritics: {{code|¤}}, {{code|¦}}, {{code|¨}}, {{code|´}}, {{code|¸}}, {{code|¼}}, {{code|½}}, and {{code|¾}}. Ironically, three of the newly added characters ({{code|Œ}}, {{code|œ}}, and {{code|Ÿ}}) had already been present in [[DEC (company)|DEC]]'s 1983 [[Multinational Character Set]] (MCS), the predecessor to ISO/IEC&nbsp;8859-1 (1987). Since their original code points were now reused for other purposes, the characters had to be reintroduced under different, less logical code points.

ISO-IR-204, a more minor modification (called '''code page&nbsp;61235''' by FreeDOS),<ref>{{cite web |url=https://github.com/FDOS/cpi/blob/master/CPIISO/codepage.txt |title=Cpi/CPIISO/Codepage.TXT at master · FDOS/Cpi |website=[[GitHub]] }}</ref> had been registered in 1998, altering ISO-8859-1 by replacing the [[universal currency sign]] (¤) with the euro sign<ref>{{cite iso-ir |number=204 |title=Supplementary set for Latin-1 alternative with EURO SIGN |sponsor=ITS Information Technology Standardization |date=1998-09-16}}</ref> (the same substitution made by ISO-8859-15).

=== Windows-1252 ===
The popular [[Windows-1252]] character set adds all the missing characters provided by [[ISO/IEC&nbsp;8859-15]], plus a number of typographic symbols, by replacing the rarely used C1 controls in the range 128 to 159 ([[hexadecimal|hex]] 80 to 9F). It is very common for Windows-1252 text to be mislabelled as ISO-8859-1. A common result was that all the quotes and apostrophes (produced by "smart quotes" in word-processing software) were replaced with question marks or boxes on non-Windows operating systems, making text difficult to read. Many Web browsers and e-mail clients will interpret ISO-8859-1 control codes as Windows-1252 characters, and that behavior was later standardized in [[HTML5]].<ref>{{cite web |last=van Kesteren |first=Anne |url=https://encoding.spec.whatwg.org/#names-and-labels |work=Encoding Standard |title=5.2 Names and labels |publisher=[[WHATWG]] |date=27 January 2015 |access-date=4 February 2015 |archive-url=https://web.archive.org/web/20150204174315/https://encoding.spec.whatwg.org/#names-and-labels |archive-date=4 February 2015 |url-status=live}}</ref>

=== Mac Roman ===
The [[Apple Macintosh]] computer introduced a character encoding called [[Mac Roman]] in 1984. It was meant to be suitable for Western European [[desktop publishing]]. It is a superset of ASCII, and has most of the characters that are in ISO-8859-1 and all the extra characters from Windows-1252, but in a totally different arrangement. The few printable characters that are in ISO/IEC&nbsp;8859-1, but not in this set, are often a source of trouble when editing text on Web sites using older Macintosh browsers, including the last version of [[Internet Explorer for Mac]].

=== Other ===
[[DOS]] has [[code page 850]], which has all printable characters that ISO-8859-1 has, albeit in a totally different arrangement, plus the most widely used [[graphic character]]s from [[code page 437|code page&nbsp;437]].

Several [[EBCDIC]] code pages were purposely designed to have the same set of characters as ISO-8859-1, to allow easy conversion between them.
